To all whom t may concern:

Be it known that I, JOHN L MILLER, a citizen` of the "Unite-d States,residing at Monroe, in the county of Walton and State of Georgia,have-invented new and useful Improvements in Hammers', of `which thefollowing isa specicationl j The present invention relates toimprovements in hammers. v

In carrying out my invention it is my purpose to provide a hammer,primarily adapted for 'use in applying shi'nglesiupon 'a building, vbutof course` applicable for other purposes, which .shall provide meanswhereby the nails will be automatically and consecutivelyfed between apair of spring pressed jaws in a proper position toerated'upo'n by 'a-reciprocatory plunger or what may be termed the hammer proper.

I also aim to,construct ya hammer of this.

-character which shall be providedv with'a nail -magazine chamber, andwhich shall have a reciprocatory plungerprovidedwith a nail liftingelement which is disposed within'the'lnailv magazine, and which'upon anupwardfmovement of the plunger shall elevate a single nail and depositlthe same within a chute to permit of the said nail with a simple buteHective means venting the clogging of the nails at,tlie' de `liverypassage.d v

gravitating within the chute, and being delivered between a pair ofspring pressed holding jaws, and. in proper positionto be operated uponby the plunger when the said p unger is move-dl toward the jaws. i

I also propose to provide the hammer for pre- -A further Aobject of theinventionis the provision, with a hammer yof this character,

of a-nail puller and a ,shingle cutter. Bothv of these members beingnormally retained above the nail4 outletv end of the hammer so as not tointerfere with ,the y movement of the plunger operating sleeve, the saidleevep being provided with means v'vliereby the samemay be brought-into'contact 'with the however,

cutter member' to force the. end thereof below the hammer-to .split-ashingle. With the above recited :objects in view,

and' others which will Aappear as the nature` of theI invention ismorefully understood, the improvement resides-inthe construction,combination and'operative arrangement of parts set forthvin thefollowingspecification, and alluded'` to with partioularity inthe claims' 14'.. iY

entirety. The hammer includes a tubular Figure -1A is a perspective l iReferrin now` to the drawings in detail, l the'numera 1 designates thehammer in itsv member or barrel 2 whichhas its upper end connectedthrough the medium of a splitl y' collar 4 with a nail magazine chamber3.'.

'The collar 4 has its free ends provided with ears 5 which have suitableopenings for the reception'of a bolt 6 which thumb nut 7 and therebyeffectively but removably connects the barrel 2 with the chamber 3. Thellower eXtremit of the'bar rel 2 is enlarged, and. is providsed withoppositely arranged flat faces 8 which are bico-ac'ts with a aov-furcat'ed at their extremitiesl to provide for the reception of jawmembers 9 and'lO re'- spectively. These jaws are of a size suicient tosnugly close theopenings provided by the bifurcations, andthe said jawshave their inner faces Contact with each other throughthev medium offlat springs 12 and 13 respectively which are connected to the outerfaces of the jaws v and to the flattened faces 8 of the barrel'2.

"flatand are forced into The meeting faces' of the jaws are each provided withv a co-acting substantially semij ,circular depression orpassa e 14, the said passages communicating wit enlarged depressions"15, the said depressions bemg dis-v posed directly below .the outlettially the passage 14,' and to also sustain the head of the nail 1n aposition to be 'operated upon,

in a'imanner which will presently setA `forth.

"The numeral 16 designates'the plun er or hammer, the' same being'arranged withl'nthe Abore of the 4'tube or barrel 2. This lunger has itslower face, 9 and 102, provided with a frusto-eonical head 17. l eThe'numeral 18 designates a sleeve or run-v nerA which surrounds thetube or barrel 2,

. and which is provided witlia 'removable pin mouthof the barrel 1.These'l depressions arel 'substan-- cone-shaped so as to direct a nailto 1 or that adjacent t e 'aWs if v,substantially l 19 that passesthrough an elongated slot 18', provided in the barrel 2, and whichconnects the runner with the hammer 16. The enlarged end of the tube orbarrel provides a shoulder 18a which serves as a stop for limiting the.downward movement 'of t-he runner l and thel consequent downwardmovement of the hammer. The sleeve'may serve asa stop for limiting themovementl of the runner when the hammer is raised, or the slo-t 18' mayterminate a suitable distance away'from thisend ofthe barrel-toprovideja wall which will be contacted by the pin19, and thus halt theupward 'movement of the runner and hammer.

` The magazine or nail chamber 3 is preferably -cone-shaped, and has itsupper and normally closed top provided with a nail inlet o ening 20which is normallyclosed througg of the chamber opposite the plug 21 hasits upper extremity beveledor inclined toward the said opening as at 22,the said wall terminating a suitable distance away from a curved innerportion 23 of the top. The top opposite the passage thus provided is.enlarged to provide a nail receivin chamber 24 which communicates witha nai chute 25. The slide vor runner 18 is provided with a depressionwhich communicates with its bore, and throu h which the chute 25 ispassed, and where ythe said chute will not interfere with thereciprocatory movement-*of the member 18, but which, as 21.-"matter offact provides an additional means for sustaining the runner fromrevolving upon the tube or barrel. The chute 25 communicates with thebore of the barrel directly above the jaws 9 and 10, the communica-tingpassage being downwardly inclined so as to direct the nails to thedepressions 15 and from thence to the passage `14 in a proper positionto be operated upon by the hammer in its downward movement. The nailmagazine 3 at its lower end, or at itsend ad'acent the bar- 'rel 2 isprovided with a cup s aped member 26, the same being centrally providedwith an'opening 27 through which extends to the interior of the magazinechamber 3, a nail lift 28which is connected to the upper extremity ofthe hammer 16. This nail lift is v substantiallyl U-shaped -in crosssection and Y. 1s preferably constructed-of resilient materia The lifthas its upper extremity curved as at 29, and is of a width 4or sizesuicient to snugly enter the passage arranged between the walls 22 and23. The

,l extremity of the wall 22 is provided with an oset portion or lip 30,the same being adapted to engage with the pointed end of the nail and toremove the said nailV from the nail engaging end 29 of the lift 28 when.the said endV is partially withdrawn from within thenail receivingchamber 24. It

will hej noted that whenthe hammer 16 has the medium of a plug 21. The,wallA` been forced downwardly 'to drive home a nail from between thejaws 9 and 10, the lift 28 is in a position to receive one of the lnailsfrom within lthe chamber 3 and an upward movement of the hammer willcause the said lift to deliver a nail to the chute 25 and def posit thesame between the jawsin a position to be actedfupon by the hammer so thefirst operation ofthe hammer will be to raise the same to allow the nailto be thus positioned. v

From practice it has been found that occasionsv arise upon which thenails become clogged at the passage between the chamber 3 and thechamber 24, and to-overcome vthis clogging I provide the top of themagazine with an opening'31which is dis bsed directly opposite thepassage, and which is provided with a spring pressed plunger 32. Thecurved extremity 29, may be, and pref- "erablyis provided with aV-shaped depression which receives the head of the nail and permits theshank thereof engaging between the sidewalls ofl the cross.-sectional-U- shaped. lift, but as this is also true of a lift which' does not haveits end slotted, the said slot is not an absolute requirement. 4Arranged upon one of the faces of the enlarged end of the tube or barrelis a cylinder 33 having both its top and bottom provided with reducedopenings through which pass a stem 34. The stem 34 is provided with aflange or collar 35 adjacent its upper end, the said'flange beingarranged within the cylinder, and surrounding the portion of the stemwithin the cylinder and 'exertin a tension between the lower wall of thecy in- 'der and the flange 35 is a helical spring 36. The lower end ofthe stem which projects through Y the cylinder is provided with a .knifehead 37 which, through the medium of the spring 36 is disposed above thelower extremity of the end of the barrel. The slide or runner 18 has itslower wall formed with an opening r38, the said opening or depressionbeing arranged in the pathof the up'` Wardly extending portion of thestemf34, and which normally receives the said end of the stem withoutacting upon the same.

v -The numeral 39 designates an abutment 115 member which is arrangedwithinanopening disposed transversely of and which communicates with therecess or openin 34. This ,abutment member is provided with a headedstem 40 and is further provided with 120 a helical spring 41 whichexerts a tension to sustain the abutment. member 39 out of the openingor depression 38. When pressure is exerted upon the headed member 40 toy cause the abutment member 39 to be ar- 125 ranger within the openingor depression 38,l and when the slide 18 is forced downwardly,

the said abutment member will contact with the upper projecting portionof the stem 34 to cause the said stem to be forced downf wardly topermit of the knife head 37 acting u'pon a shingle or the like to splitor sever the same.

The enlarged end 8 of the barrel 2, diametrically opposite the portionprovided with the cylinder 33 has connected thereto a bracket" memberwhich includes a pair of spaced ears 42 and pivota-lly connected as at43 between the said ears is the upper eX- tremity of a nail extractor44. The extractor comprises a flat member having its lower extremityoffset and provided with a V-shaped depression 45, and the said eX-tractor is normally sustained in proper relation with the hammer throughthe medium of a flattened spring 46which is connected as at 47 to theend of the barrel and which has its free end bearing against the innerflat face of the extractor 44. The flat spring 46 is so arranged as tocontact' with the extractor to sustain the same ata desired anglewithvrelation to the barrel so the same may be swung to a properposition to extract a nail.

From the above description, taken in connection with the accompanyingdrawings the simplicity, as well as the advantages of the device, will,it is thought be apparent to those skilled in the art to which suchinventions appertain without further detailed description. v

Having thus described theinventiomwhat I claim isz l. Ina hammer of theclass set forth, a nail magazine, a nail receivingv chambercommunicating wit-h the magazine and disposed at the top thereof, adelivery chute communicating with the chamber, spring pressed jawsarranged below the outlet ppi-t of the chute, a cup shaped member havinga central opening secured within the lower end of the magazine, a barrelremovably connected with the magazine, a plunger within the barrel, asleeve surrounding the barrel and connected with the plunger, afleirible nail lift connected with the plunger and passing through theopening of the cup shaped member to within the magazine, the

said lift being constructed and arranged toy raise a nail from withinthe magazine to deposit the same within the nail receiving chamber fromwhich it gravitates through the said chute to be received between thesaid jaws, which jaws are arranged withinthepath of movement of theplunger.
